Radio communication apparatus, radio communication system, and method of switching communication mode

A radio communication system, comprising:

• a mobile terminal;
• and
• a radio communication apparatus that provides the mobile terminal with information through various communication modes,
• wherein the radio communication apparatus includes
• a determination unit that determines whether to perform switching from a first communication mode to a second communication mode based on communication information used in communication between the mobile terminal and the radio communication apparatus;
• a logical channel establishment unit that newly establishes a logical channel by using a first logical channel corresponding to the first communication mode as a second logical channel corresponding to the second communication mode, based on a determination result of the determination unit;
• a transport channel conversion unit that converts a transport channel of the second logical channel from a first transport channel corresponding to the first communication mode to a second transport channel corresponding to the second communication mode;
• and
• a communication switching unit that switches to the second communication mode using the second logical channel and the second transport channel.

A method of switching a communication mode, comprising:

• storing communication information used in communication between a mobile terminal and an own apparatus in a storage device;
• determining whether to perform switching from a first communication mode to a second communication mode based on the communication information stored in the storage device;
• newly establishing a logical channel by using a first logical channel corresponding to the first communication mode as a second logical channel corresponding to the second communication mode, based on a determination result of the determining;
• converting a transport channel of the second logical channel from a first transport channel corresponding to the first communication mode to a second transport channel corresponding to the second communication mode;
• and
• switching to the second communication mode using the second logical channel and the second transport channel.

A radio communication system, comprising:

• a mobile terminal;
• and
• a radio communication apparatus that provides the mobile terminal with information through various communication modes,
• wherein the radio communication apparatus includes
• a control unit that determines whether to perform switching from a first communication mode to a second communication mode based on communication information used in communication between the mobile terminal and the radio communication apparatus;
• and
• a baseband processing unit that newly establishes a logical channel by using a first logical channel corresponding to the first communication mode as a second logical channel corresponding to the second communication mode, based on a determination result of the determination unit, converts a transport channel of the second logical channel from a first transport channel corresponding to the first communication mode to a second transport channel corresponding to the second communication mode, and switches to the second communication mode using the second logical channel and the second transport channel.
